- Illumina HumanHT-12 V3.0 expression beadchip
Description
Resistance to platinum compounds represents a major obstacle to the cure of ovarian carcinoma. The molecular profiling of drug-sensitive and drug-resistant cells may be helpful to clarify if altered gene expression can contribute to the drug-resistant phenotype. The expression pattern of three ovarian carcinoma cell lines was examined. The analysis revealed the modulation of several genes in the two platinum-resistant cell lines as compared to parental platinum-sensitive cells. The integration of the information obtained through gene expression analysis may be useful to clarify the specific molecular alterations of factors and pathway favouring survival of tumor cells.

Description
Significant recent progress has been made with understanding eosinophilic gastrointestinal disorders (EGIDs) yet most studies have focused on eosinophilic esophagitis (EoE). Herein, we aimed to provide fundamental information about the molecular characteristics of eosinophilic gastritis (EG).
Publication Title
Histologic eosinophilic gastritis is a systemic disorder associated with blood and extragastric eosinophilia, TH2 immunity, and a unique gastric transcriptome.

Description
cdipt is an essential gene in the synthesis of phosphatidylinositol (PtdIns) in the zebrafish, Danio rerio. The zebrafish mutant cdipt^hi559Tg (ZL782) carries a retroviral insertion which inactivates cdipt. Homozygous mutants exhibit hepatocellular endoplasmic reticulum (ER) stress and non-alcoholic fatty liver disease (NAFLD) pathologies at 5 days post fertilization (dpf). This study reveals a novel link between PtdIns, ER stress, and steatosis.
Publication Title
Lack of de novo phosphatidylinositol synthesis leads to endoplasmic reticulum stress and hepatic steatosis in cdipt-deficient zebrafish.

Description
Eosinophils are major effector cells in type 2 inflammatory responses and become activated in response to IL-4 and IL-33, yet the molecular mechanism remains unclear. We examined the direct effect of these cytokines on eosinophils and demonstrated that murine eosinophils respond to IL-4 and IL-33 by phosphorylation of STAT-6 and NFkB, respectively. RNA sequencing analysis of murine eosinophils indicated that IL-33 regulates 519 genes, whereas IL-4 regulates only 28 genes, including 19 IL-33-regulated genes. Interestingly, IL-33 induced eosinophil activation via two distinct mechanisms, IL-4 independent and IL-4 secretion/auto-stimulation dependent. Anti-IL-4 or anti-IL-4Ra antibody-treated eosinophils, as well as Il4- or Stat6-deficient eosinophils, had attenuated protein secretion of a subset of IL-33-induced genes, including Retnla and Ccl17. However, the induction of most IL-33-regulated transcripts (e.g. Il6 and Il13) was IL-4 independent and blocked by NFkB inhibition. Indeed, IL-33 induced the rapid release of pre-formed IL-4 protein from eosinophils by an NFkB-dependent mechanism. Thus, we have identified a novel activation pathway in murine eosinophils that is induced by IL-33 and differentially dependent upon IL-4. These data suggest that IL-4 plays a critical role in auto-amplification of IL-33-induced eosinophil activation and could be a potential target for therapeutic approaches in IL-33-related eosinophil-associated diseases. Overall design: Low density bone marrow derived murine eosinophils were generated in culture over the period of 14 days. Eosinophils were activated by either IL-33 or IL-4 at 10 ng/ml for 1hr and 4hr. RNA was collected and subjected to next generation sequencing.

Description
The goal of this study is to investigate the molecular mechanism of lhx1 on regulation of pronephros formation during the early embryonic development. In the vertebrate embryo the kidney is derived from the intermediate mesoderm. The LIM-class homeobox transcription factor lhx1 is expressed early in the intermediate mesoderm and is one of the first genes to be expressed in the nephric mesenchyme. The animal cap cells can be induced by treatment of activin and retinoic acid to differentiate into pronephros tissue. In this study we investigated the role of Lhx1 in differentiation of pronephros by depleting lhx1 in the organ culture system. We generated the gene expression profile of early pronephros tissue, and demonstrated that expression of genes from all the kidney domains is affected by the absence of lhx1. Taken together our results highlight an essential role for Lhx1 in pronephros formation.

We used RNA sequencing to identify differentially expressed genes during esophageal epithelial differentiation and in the presence of interleukin 13 using an air-liquid interface culture system. Overall design: RNA sequencing was performed on a human esophageal epithelial cell line (EPC2-hTERT) grown submerged (day 8) or at the air-liquid interface (ALI) (day 14, untreated or treated with interleukin 13 [100 ng/mL])
